I have a new one on me. I had the front end up, so I could check for leaks after replacing the rod change seal and cam seal.
I saw grease splattered on the trans housing and the sub-frame fire wall, not a lot. I could not see an obvious tear or hole, but I decided to replace the boot anyway.
I have it apart and the boot has no holes or tears. The straps for the boot were snug on both the large end and the small end.
I have never had a pot joint "burp" itself. I don't think I overfilled it, but it was a while ago.
I will put it back together, but this is an odd one.
Happy Fourth!
